TightVNC is a free remote control software package derived from the popular VNC software. With TightVNC, you can see the desktop of a remote machine and control it with your local mouse and keyboard, just like you would do it sitting in the front of that computer.

TightVNC can be used to perform remote control and administration tasks in Windows, Unix and mixed network environments. It can be very helpful in distance learning and remote customer support.

TightVNC provides these features which are otherwise absent in standard VNC:

- Server and Viewer for Windows: There were many enhancements and fixes related to keyboard handling. Keyboard handling is the primary focus of this Beta version.- Server for Windows: A bug with clipboard handling has been fixed. When running as a service, TightVNC Server could crash if a user copied something to the clipboard.- Server for Windows: There was a bug which caused the control interface to crash if the server had a lot of IP addresses. The problem has been resolved.- Server for Windows: File uploads could fail at changing file modification timestamps. This bug has been fixed.- Server for Windows: Fixed a bug with Web access not enabled by default.- Viewer for Windows: When run with the -help command-line option, the viewer listed a lot of options it actually does not support. This has been fixed. Unsupported options have been removed, supported options have received better documentation.- Viewer for Windows: Unsupported command-line options were treated as host names to connect to. Now the viewer will report error messages on discovering unknown options in the command line.- Viewer for Windows: The viewer used to connect to nowhere if it could not read the specified .vnc file. Now it should exit correctly after showing the error message.- Viewer for Windows: In connection options, the check box "Request shared session" will be disabled after the connection has been established.- There were other minor improvements and fixes.
